PAPER BAG.

Application led May 26, 1922. Serial No. 563,899.

One object is to produce a device of this.

nature in which the bottom of the bag shall not be formed by meetingedges of the paper, but by the solid middle portion of the strip so thatit may be more efficient as a lining for garbage pails and the like.

parts in all views.

Another object is to produce the bag in a simple manner so that it maybe readily manufactured by machines.

With these and other objects in View, the invention resides in theblank, the essential features of which are hereinafterv fully described,are illustrated in the accompanying drawing, and are particularlypointed out in the appended claims.

In the drawings Figure 1 is a flat view of a blank for formin vthe bag.l i

igure 2 is a perspective showing the blank in partly folded condition.

Figure 3 is a perspective of the device in substantially foldedcondition. y' Figure 4 shows the'finished bag in open condition. 4

Figure 5 is a sectional view of the device as shown in Figure 4.

Likel characters of reference refer to like Referring to the drawinor indetail, 10 represents an oblong blank ofD paper, the center of which isshown at 11. Radiating from the point 11 are 1on1 lines 12, 13, 14,15,16 and `17 17". Lines 12 and 13 completely divide the blank 10 fromend to end. Lines 14 and 15 are arranged at angles of 45 to the lines 12and 13, respectively, and are themselves 90 apart. Lines 17 and 16 aresimilarly arranged on the-opposite side of lines 12 and 13. Lines 14,15, 16 and 17 are all of the same length, lines 14 and 15 beingconnected at their outerends by a line 18 and lines 16 and 17 beingconnected by a. similar line 19. From the extremities of the lines 18and 19 are return lines 20, 21, 22 and 23.

Extending from the ends of lines 18 and 19, and parallel with lines 12and 13 are lines 24, 25, 26 and 27, and beyond theintersection of lines20 and 21 and of 22 and 23 are short lines 28, 29, 30 and 31 whichextend to the edge of the blank. I

In folding the blank, the parts are brought tothe position shown inFigure 2, lines 18 and 19moving u and lines 12 and 13 moving inwardly.Such movement'4 naturally causes linesA 24, 25,'26 and 27 to moveoutwardly, the edges folding along the short lines 28, 29, 30 and 31 toeffect a lapping of the edges of the device, which edges are pastedtogether as indicated by' the shading.

lVhen'completely folded as shown in Figure 3, the point 11 and thepoints of intersection of the lines 28 and 29 ,and lines 30 and 31, lieside by side and the. bottom of the folded bag s pointed. Thus thesquare bounded by the-lines 14, 15, 2O and 21 is folded on the diagonalline 18 and the two right triangles are positioned in contact. They arepasted in this position. In like manner the two triangles forming thesquare bounded by the lines 16, 17, 22 and 23 are brought together andpasted. v

The folding of the blank will be better understood when it is statedthat the blank is first folded on itself on the alined lines 17K whichextend throughowt the width of the blank. The folded blank is then againfolded on the lines 12 and 13. The folded blank is then folded on thelines 24 andy 25 after which the corner' portion of the folded blank isfolded forwardly upon the major portion of the folded blank, the latterfold being on the lines 14 and 21 which are then in parallelism andclose proximity. Subsequently to the said folding in 1the se uenceindicated the folded blank is /open and paste is applied in the mannerdescribed for the completion of the bag.

When it is desired to open the ceive goods, it will be seen that th and19 will form two of the bou daries of the bottom, and that the other twoboundab'gto re- I ines 18l ries will be determined by lines connecting ythe proportions; and while I have described what I deem to be the mostdesirable embodiment of my invention, it is obvious that. many of thedetails may be varied Without l in any way departing from the spirit ofmy invention, and I therefore do not limit 1nyself to the exa-ct detailsof construction herein set fonth nor to-anything less than the who-le ofmy invention limited only by the appended claims.

What is claimed as new is l. An oblong blank ot paper for forming apaper bag, characterized by an unevenA number of longitudinal :toldlines extending substantially throughout its length, and by anevennumber of medial fold lines, the

, latter constituting' two squares with their inner corners together incoincidence with the intermediate. longitudinal fold line and whosewalls are foldable with respect to each other, and by fold lines spacedapart and disposed at right angles to the longitudinal fold lines andextending between square corners in coincidence with the outerlongitudinal fold lines.

2. An oblong blank of paperfor forming a paper bag, characterized by anuneven number of longitudinal fold lines extending substantially[throughout its length, and

. by an even number of medial fold llnes, Ithe latter 4constituting rtwosquares with their inner corners together in coincidence with theintermediate longitudinal fold line and who-se walls are foldable withrespect' to each other, and by fold lines spaced apart and disposed atright angles fto the longitudinal fold lines and `extending betweensquare corners in coinciden-ce with they outer longitudinal fold lines;the said blank being also provided with slots at the ends of thelongitudinal fold lines.

3. An oblong blank of paper for forming a paper bag, characterized by anuneven number ot' longitudinal fold lines extendingsubstantiallythroughout its length, and by an even number of medial foldlines, the latter constituting two squares with their inner cornerstogether in coincidence with the intermediate longitudinal fold line andwhose walls are oldable with respect to each' other. v

4. An oblong blank of paper for forming a paper bag characterized by an`uneven number of longitudinal fold lines extending substantiallythroughout its length, and by an even number of medial fold lines, theAlatter constituting two squares with their inner corners together incoincidence with the intermediate longitudinal fold line and whose wallsare foldable with respect to each other; the said blank being alsoprovided with slots at the ends of the longitudinal fold lines.

In testimony whereof I have afixed my signature.
